I live in California. California is ostensibly part of the US.
I'll say this: headhunters are worthless after you turn 50. What works is jobs lists (like right here on HN), Craigslist and word of mouth.
I'm 115 and still working as a programmer, things haven't changed so much since the 30s anyway, we were serverless back then as well, primarily coze we had neither servers nor computers.
